STOVE.

SPECIFICATION forming part of Letters Patent No. 253,144, dated January31, 1882.

7 Application filed February 17, 1881. (Model) To all whom it mayconcern:

Dayton, .in the county of Montgomery and State of Ohio, have inventedcertain new and useful Improvements in Stoves; and I do hereby declarethe following to be a full, clear, and exact description of the same.

The object. of my invention is to provide a stove or heater in which, bythe use of a down- 10 ward draft, there shall be the most perfectcombustion, complete consumption of the fuel, and the least vpossibleescape of unconsumed gas, and a reduced percentage of smoke.

With this object in view I have planned, ar-

ranged, and constructed the different elements of a stove or heater inthe manner herein shown and described; and my invention consists incertain devices or elements and the arrangement and combination of thoseelements and others, as hereinafter specifically set forth in theclaims.

Referring to the drawings forming apart hereof, Figure 1 is a verticalcentral section from side to side of a stove embodying my invention.Fig. 2 is a like section from front to back;-Fig. 3, a horizontalsection on line 00 a of Fig. 1; Fig. 4, a detail showing an optionalarrangement of the mica lights; Fig. 5, a detail view, hereinafterdescribed; and Fig.

0 6, a central vertical section of a modified arrange'ment andconstruction of the principal elements of a stove or heater embodying myinvention.

Like letters of reference refer to like parts 5 in all of the figures.

Thejacket or shell A of the stove may be of any shape or configurationdesired, and may be supported upon any suitable base, B, provided with achamber, 0, adapted for the insertion 40 and withdrawal of a suitableash'pan, D, the

material of all of these and the remaining elements of the stove being amatter of discretion with the constructer.

The ash-chamber G is separated from the upper portion of the stove by apartition provided with a register consisting of a radiallyslotted disk,F, surmounted by a like disk, G, centrally pivoted thereto, and havingA-ridges g disposed thereon between the slots, and a so handle, a,projecting through the shell A, to

permit of the operation of the disk Gfrom the outside of the shell.

The shell A is provided with a door, I, and exit-draft tube T, of usualconstruction and arran gement. 5 5

An exit-tube, S, may be provided for the ashchamber 0, which tube may besuitably connected with the draft-tube T for the purpose of establishingin the usual manner a draft to carry off the dust occasioned by theremoval of the ash-pan.

In any suitable manner, preferably that shown in Fig. 6, I suspendcentrally within the shell, and from or upon a flange, i, at the topthereof, a centrally-located cylinder, J, which extends nearly to thebottom third of the shell, and I form integrally therewith, or suitablysupport thereon, a flaring fire-pot, I, thelower edge of whichisscalloped or notched, as shown at 1). Transverse straight or curved 7opipes c are constructed and attached to the shell A and to the cylinderJ at a point near the lower end of the latter and at desired '10-calities in the former, as clearly shown in Figs.

1, 2, and 6.

Concentrically within cylinder J is suitably suspended the reservoirproper, H, of the stove. In Fig. 6 I have shown the preferable manner ofsupporting this element.

Upon the flange i of the shell A rests a ring, k, perforated at d andadapted to receive and retain the flaring mouth of the reservoir; orsaid ring may be cast integral therewith.

It will be observed that the reservoir extends ashort distance below thepipes e and is flanged at itslower end at c.

Instead of constructing the fire-pot I integral with or to be supportedby cylinder J, said pot I may be suspended from the flange of thereservoir. The flaring mouth of the res- 9o ervoir is surmounted with apractically airtight cover, N n, the part n being adapted to move uponthe part N, register-like, as is common, and both parts moving about theremaining elements, which are located as here- 5 inafter described.

The top proper of the stove consists of two parts, similar in operationand construction to those just described, the stationary part N, and amovable part provided with ahandle, n,

by which it is operated, register-like, to open and close.

Supported preferably by the stationary part N of the cover of the stoveis the central main draft flue or cylinder, M, arranged concentrieallyto the before-described elements, and having induction-aperture m at itsupper end, the flue extending a trifle below the lower end of thereservoir H.

From and upon the top of flue M is supportedahollow rod, L, whichextends within the fire'pot I, and has attached thereto or formedthereon a cone-shaped base, K. The rod L is screw-threaded at its top f,and is provided with a nut,f,;or, as shown at Fig. 1, the nutf may befixed, and the ornamental handle 0 may be attached thereto. The base Kis provided with ribs or corrugations K, as shown at Fig. 5, and thedistance that said corrugations shall extend upon the body of the baseis a matter of option, except that at the upper end of saidbase suchform and size should be secured as will fit within the fine M.

At Fig. 4 I have shown a desirable manner of constructing the micawindows of stoves of this character, in which the mica R is slantedinwardly, as shown, leaving a slight opening, a, at the sides and b atthe bottom, as clearly understood by reference to the figure; but I donot herein seek to secure such construction, but will reserve such for afuture application.

It will be seen that the principal elements herein shown and describedare essentially a fire-pot the base of which is adjustable therein and amagazine the cover of which is airtight, the only air which can besupplied being conducted downwardly into the pot and below the source ofsupply of coal, for purposes set forth in the operation, as hereinafterdescribed.

The operation of my invention is as follows: The base K having, by meansof the nutf and rod L, been set at such a point as to prevent fuel frompassing through, snfficient coal is introduced through the covers N Ninto the firepot I, and a fire is started upon the top of the coal thusintroduced. After said coal has become sufiiciently ignited a fullsupply of coal is put within the reservoir, and it continually falls asfast as that in the fire-pot is consumed. By observing the arrows in thedifferent fig ures the currents of air can be clearly traced. First andalways there is a mild current entering at the top of the hollow rod L,passing downwardly therethrough, beneath the base K, thence upwardly andbetween the shell A and cylinder J, and finally out the chimneyflue T.This current is permanent and carries the smoke and products ofcombustion during a slow burning of the fire, and is designed to servethe purpose of keeping the fire, for at such times the upper end of baseK is elevated within and closes the lower end of the main draft-flue Meither completely or nearly so, depending npon the form of said upperend and the extent of the corrugations K, which may be advantageouslyprojected within the flue M to supply a limited quantity of air directto the fire-pot. From this point in the operation of the stove let it beassumed that the fire is desired to be under full headway or burning forthe purpose of heating. Now the base K is depressed a trifle below thefire-pot, as shown in Fig.6, and a direct downward draft is suppliedthrough apertures m at the top of flue M, and this draft is fedcentrally within the body of coal in the fire-pot I, and as there is noother escape it passes between the lower edges of the pot I and the baseK, carrying with it the gas formed by heating the superimposed coal andcausing its complete combustion by contact with the incandescent coalbelow, thus greatly increasing the heat derived and diminishing thequantity of smoke. The draft, continuing, takes the course describedwith reference to the current entering the pipe or rod L, and with itpasses out of the chimney-fine T. Outside air is excluded from contactwith the fire at all other points and only enters the pipes c to beheated and to rise and pass out of the perforations d to heat the roomor be conducted by pipes to other apartments. The air thus entering thepipes e, L, and M-is cool, and it serves to keep the body of coal in thereservoir comparatively cool, so that no gas is generated therefromexcept in close proximityto the fire-pot, where the descending draftquickly conveys it to beconsumed. The ashes collect upon the register G.The -ridges act to guide the ashes through the same into the pan D.

To prevent any upward draft the register is opened only to collect theashes and is closed at all other times.

Having described my invention and its operation, what I claim as new,and wish to secure by' Letters Patent, is

1. In a stove or heater, a bottomless fire-pot connected to a magazinehaving an air-tight cover, said fire-pot having a centrally-supportedbase provided with acentral downwarddraft flue, in combination with theshell of the stove, provided with a chimney-flue and an airtight base,substantially as shown and described.

2. The combination of a bottomless fire-pot, a coneshaped base providedwith an adjustable supporting-rod, and a main downwarddraft flue,substantially as shown and described.

3. The combination of the air-tight shell, the suspended bottomlessfire-pot, the adjustablysuspended base, the register G, and theashchamber 0, substantially as shown and described.

4. In a reservoir-stove, the combination of the reservoir, a suspendedfire-pot attached thereto, a central main downward-draft flue, and anadjnstably-suspended base, substantially as shown and described.

5. In a reservoir stove or heater, the combination of acentrally-suspended downwardreservoir-flange and supporting a main down-Ward-draft flue, which terminates within the fire-pot, substantially asshown and described. 7. The combination of the flaring fire-pot I,notched at its lower edge, and the base K, conical in shape, ribbed, asshown, and adjustablysuspendcd therein, as shown and described.
